Soil greenhouse gas fluxes following conventional selective and reduced-impact logging in a Congo Basin rainforest
; ; ; (Biogeochemistry, 2020-11-03)
Selective logging is among the main causes of tropical forest degradation, but little is known about its effects on greenhouse gas (GHG) fluxes from highly weathered Ferralsol soils in Africa. We measured soil CO2, N2O, ... -
Soil organic carbon allocation and dynamics under perennial energy crops and their feedbacks with soil microbial biomass and activity
; (Soil Use and Management, 2020)
The cultivation of perennial instead of annual energy crops has received growing interest. Previous studies identified numerous beneficial effects of perennial energy crop (PEC) cultivation for the agricultural landscape ... -
Soil organic matter turnover rates increase to match increased inputs in grazed grasslands
; ; ; ; ; ; ; (Biogeochemistry, 2021-08-27)
Managed grasslands have the potential to store carbon (C) and partially mitigate climate change. However, it remains difficult to predict potential C storage under a given soil or management practice. To study C storage ... -

Solar Activity Driven 27‐Day Signatures in Ionospheric Electron and Molecular Oxygen Densities
; (Journal of Geophysical Research: Space Physics, 2022-09-13)
The complex interactions in the upper atmosphere, which control the height‐dependent ionospheric response to the 27‐day solar rotation period, are investigated with the superposed epoch analysis technique. 27‐day signatures ... -
Solar noble gases in an iron meteorite indicate terrestrial mantle signatures derive from Earth’s core
; ; ; ; (Communications Earth & Environment, 2021-05-14)
Noble gases are important tracers of planetary accretion and acquisition of volatiles to planetary atmospheres and interiors. Earth’s mantle hosts solar-type helium and neon for which 20Ne/22Ne ratios ... -
Solving the system of radiation magnetohydrodynamics for solar physical simulations in 3d
(Univ. Freiburg (Breisgau), 2003)In this study we present a finite-volumen scheme for solving the equations of radiation magnetohydrodynamics in two and three space dimensions. Among other applications this system is used to model the plasma in the solar ... -
Some Preliminary Results on the Early Holocene Shore Displacement in the Oskarshamn Area, South Eastern Sweden
(E&G – Quaternary Science Journal; Vol.35, No. 1)In zwei 16 bzw. 26 m über Meeresspiegel gelegenen Seen sind Pollen- und Sedimentanalysen durchgeführt worden. Der Beginn der präborealen Chronozone ist hier durch eine Regression gekennzeichnet, die wahrscheinlich durch ... -
Sorption of PAHs and PAH derivatives in peat soil is affected by prehydration status: the role of SOM and sorbate properties
; (Journal of Soils and Sediments, 2020-06-23)
Purpose: Sorption of organic compounds to soil largely determines their mobility and bioavailability in ecosystems. It is well known that molecular properties of the organic sorbates affect the sorbed amounts ... -

Sound Velocity Measurements of B2‐Fe‐Ni‐Si Alloy Under High Pressure by Inelastic X‐Ray Scattering: Implications for the Composition of Earth's Core
; ; ; ; ; ; ; ; ; ; ; ; ; (Geophysical Research Letters, 2022-08-04)
Elastic properties of B2‐Fe0.67Ni0.06Si0.27 (15 wt.% Si) alloy have been investigated by combined high‐resolution inelastic X‐ray scattering and powder X‐ray diffraction in diamond anvil cells up to 100 GPa at room ... -
Source processes and spectral ground motion models of intermediate depth Vrancea (Romania) earthquakes
(Univ. Karlsruhe, 2007)For successful assessment and mitigation of earthquake hazards, it is necessary to be able to reliably predict the level of ground shaking which has to be expected from future large earthquakes. This prediction of ground ... -
